My xterm suddenly went white b-g with black text f-g. Not that I use xterm by choice, but sometimes it pops up (actually it would pop up when using Ranger in LXterminal and initiating a bash process -it doesn't any more since switching to rxvt-unicode).
Set the X colours
You will need to make or edit the file ~/.Xresources,
and add this content
When you've made any changes you want to make, run this command and then re-start Xterm:
and that command can go in the LXDE or OB autostart
Tips:
The xterm scroll bar is a little different to usual - left click on it to go down and right click on it to go up.
Xpdf
Here's a nice pdf viewer. If you set the X colors as above, or with what changes you like, Xpdf follows suite (which is a good thing on my dark themed desktop).
Tips:click and drag to select a region, then right-click and zoom to selection.
Some keys from the man page:
n
Move to the next page. Scrolls to the top of the page, unless scroll lock is turned on.
p
Move to the previous page. Scrolls to the top of the page, unless scroll lock is turned on.
<Space> or <PageDown> or <Next>
Scroll down on the current page; if already at bottom, move to next page.
<Backspace> or <Delete> or <PageUp> or <Previous>
Scroll up on the current page; if already at top, move to previous page.
g
Activate the page number text field ("goto page").
0
Set the zoom factor to 125% (ready for increment and decrement).
+
Zoom in (increment the zoom factor by 1).
-
Zoom out (decrement the zoom factor by 1).
z
Set the zoom factor to 'page' (fit page to window).
w
Set the zoom factor to 'width' (fit page width to window).
h
Set the zoom factor to 'height' (fit page height to window).
Printing
The default print command is lpr
It needs to have your printer name to print to, e.g lpr -P HP_P1102
Also you could use lp -d HP_P1102
Note that these are simply bash commands, `lp' (linux print) and `lpr' (linux print request).
The `-P' or `-d' sets the destination printer.. I couldn't find anything about print quality or greyscale! - `man lp' and `man lpr' for man pages.
